Voltage sag indices are a way of quantifying the performance of the power supply, as far as voltage sags are concerned. Indices can be defined for individual events, for individual sites, and for a whole system. A standard method for single-event methods is part of IEC standard 61000-4-30.This thesis emphasizes the importance of voltage sag indices and different methods for calculating three-phase voltage sag characteristics. Three-phase events measured in a medium network voltage over period of one month were analyzed, results examined and statistically evaluated. An algorithm for calculating voltage sag characteristics and indices was created in Matlab.

The purpose of this dissertation is to describe and analyse the effects of tourism in developing countries and the attitudes and working methods of Swedish tour operators towards sustainable tourism. We have chosen to use a qualitative research according to a hermeneutical view. We have carried through in-depth interviews with eight tour operators. The theories have been divided into the effects of tourism and sustainable tourism goals which have social, economic and environmental starting points. The empiricism describes the work and activities of the tour operators and compiles the interview material divided into attitudes on tourism effects and responsibilities.

During consultation procedures between forest owners and the Sámi, data on, e.g., reindeer lichen biomass on the current site is needed. Hitherto, the existing methods of measuring lichen cover and biomass has been either objective methods such as the Point Intercept method, which is time consuming, or some sort of subjective visual estimation, which is faster but less accurate. However, both these methods are sensitive to different observers and/or to different inventories. This paper addresses the further development and evaluation of a photographical inventory method that uses colour distribution in images to estimate lichen biomass. During the autumn of 2011 six different locations, with different grazing pressure and lichen cover, in Norrbotten county were inventoried using both the Point Intercept method and the photographical method, complemented with collection of biomass samples.

Background: A health damage that has been specifically related to nursing is pressure ulcers. Pressure ulcers are a complication caused by disease, care and treatment and can result in great suffering for the patient. Pressure ulcers can affect people both physically and psychosocially and is experienced, by most patients, as a serious and unnecessary complication of care. Today there are hundreds of identified risk factors for pressure ulcers described that can be divided into patient and care-related risk factors. A successful pressure ulcer prevention and treatment is to reduce or eliminate the underlying causes for the development of pressure ulcers, prevent deterioration and to treat existing ulcers.

In this paper five different commonly used methods of making a mount for a costume in along term display was investigated: The shaping of a mannequin and a polystyrene dressstand, the making of a gypsum torso, support made out of plexiglas and polycarbonte and athree dimensional mount on a board. The materials of the mounts were thoroughly takeninto consideration and described in the paper. One of the methods was put into practice in acase study of a Russian uniform dress coat. A gypsum torso was considered to be the mostappropriate mount in this case. The dress coat was to be displayed at the Garnisons- ochluftvärns museum in Halmstad.

The main purpose with this study is to describe teachers? use of textbooks and other teaching materials in upper secondary school (gymnasiet) in Sweden, and to discuss the use according to school subject and teacher style. Data was collected in two different ways. At first twenty classroom observations were made during lectures concerning the subjects Swedish (mothertounge), English (foreign language) and religion. Then four open interviews were carried out with the teaching teachers.

-------------------------- 4AbstractThis study is a qualitative case study in order to delineate how visible learning processes in the classroom. The study draws its theory from researcher John Hattie's findings about effective teaching. Data collection is taken from a class in grade 2 in a medium-sized Swedish municipality. The result demonstrates how the communication takes place in the classroom based on the teacher's strategies and planning in relation to pupils' interests and their own initiative. Is there a mutual feedback between teachers and students while teaching? From five perspectives, and the definition of what visible learning is all about, the results shows many good examples of excellent teaching.

In today's society we are used to regularly visit the sport arena to cheer for our favorite team, we go to the cinema to enjoy a good movie or maybe to the theatre to experience a grand performance. It has become far more common in the last years to buy tickets to these kinds of events online. To make sure that the customer will keep on buying their tickets from the online booking companies the booking experience itself has to be hassle-free and easy to understand. The customer will most likely, if possible, avoid the website if the booking itself is experienced as having problems and insecurities.  The purpose of this study is to determine some of the most fundamental designs and functions of online booking websites today as perceived by the general public.

Introduction: About 160 children with Down syndrome are born each year in Sweden. They will spend their first time in life at the neonatal departments around the country. Previous research has shown that parents in these situations have experienced an unsatisfying behaviour from the caregivers and that they are not getting the care they desire. However the research that reflects the nurses? role in these situations is sparsely studied.

At Uppsala university scientists have during the last years developed and built wave energy converters. This project is called "Lysekilsprojektet". The development has come so far that they are currently investigating how to gain profit in a mass production. For that reason they want to automate as many steps in the production as possible.The winding of the stator is one part that is being automated using industry robots. The stator is cable wound unlike many other generators.

In the new media society, social media has become an important part of many organizations' daily lives. Organizations, whether public or private, must be where their audience is and many times, these can be found on social media channels like Facebook. Leading researchers in the fields of crisis communication and relationship management believe that social media is a great tool for managing relationships between an organization and its' public, whether it's before, during or after a crisis.The purpose of this study is to examine how the Karlstad municipality use Facebook to manage civic relations before, during and after a crisis. The municipality's approach will be compared to the citizens' experiences of the municipality's communication in different stages of a crisis.The theoretical framework used in this essay is the research on crisis communication and relationship management. How these two frameworks can be integrated with social media like Facebook, is an important part of understanding how the Karlstad municipality make use of Facebook to manage civic relations and communicate before, during and after a crisis.The empirical study consists of a qualitative interview, two qualitative content analysis and an online survey.

During installation and operation of a geothermal heat pump system leakage of an antifreezing agent can appear in a borehole and leak out in surrounding groundwater. To guarantee high quality drinking water for generations to come Sweden has dedicated some areas as water protection areas. The local authority gives permits for the installation of heat pump systems within water protection areas. Before giving a permit the local authority makes an evaluation of the risks involved in installation and operation of the system within the area. By keeping a certain distance between the protected object in the area and the heat pump system the risk of polluting the protected object with an anti-freezing agent can be reduced.This thesis makes a comparison between three different methods of calculating an appropriate distance between the protected object and the heat pump system.

This paper is about the new methods and metrics used in industry and business today striving for better revenues and larger market shares. It investigates the relations between the old fordistic and tayloristic way of manufacturing and compares it to the models used in industry today for being competitive, seeking to please customers and becoming more flexible. More specific the paper is about if Six Sigma and lean production are the key for succeeding these days. SKF:s factory in Gothenburg and other companies will make an example for how these methods are used in practice.The aim is to try to answer if these systems with inherited tools and methods are the right way to get the flexibility that is needed for being able to deliver the right goods to customers and market. For a company to be flexible decisions must be made fast and needed changes must be able to be done easy and without too large costs and investments.

This paper is based on observations made in the classroom, interviews and studies ofliterature.The observations that I made during my practical training period made me believethat pupils with writing and reading problems succeeded more often with the methodsof teaching used in media education than with more traditional teaching methods.Through this study I hope to specify and define the factors that were the reasons for this. In doing so I wanted to show that you could adapt the teaching methods to reach more pupils with different kinds of learning styles.I have come to the conclusion that the following factors made the pupils with writing and reading problems succeed more often in subjects related to media education:Variety, time spent, the pupils? interests and the equipment used..

'Hir in the box' is a study about the gender perspective in packaging design and how it is today. The study deals with the product category razors, for both women and men, to examine and compare products with the same function but with different designs. Based on an analysis of how packages are designed for different sexes, information should be given on how gender-neutral packaging can be designed and used in the future to reach the market. The purpose of the study is also to contribute to future research on the subject. To fulfill the purpose of this study, nuanced and in-depth data is collected by means of a small-N-study and a qualitative study in the form of open group interviews where the survey units are reviewed and discussed.
